The Simple Life star, who is part of the ensemble cast in the upcoming Tina Fey-executive produced NBC series, Great News, opened up to ET's Leanne Aguilera at the Television Critics Association press tour in Pasadena, California, on Wednesday about diving fully into the scripted world with this latest role.

"This script came, and it came really fast and I read it. The moment I read it, I was like, I really, really want this part," the 35-year-old actress revealed. "As soon as I got it, we were shooting, like, five days later. And so, I just had to jump right into it. I had no idea what I was walking into."

Richie, who plays Portia in the newsroom comedy, shed some light on what to expect from her character on the show.

"Chuck [John Michael Higgins] and Portia are the on-air talent at this news station. We are polar opposites," she explained. "Chuck is a traditional news anchor type of person ... Portia is very now and very forward."

Meanwhile, as Richie is getting back to the small screen, her dad, Lionel Richie, is getting back to the stage!
